Consider a signal x (t) whose Fourier transform X(f) is given below. Note that the value at the top of each delta function is its weight, i.e., the delta at 20 Hz is given by 78(ƒ - 20). 11π 4 -80 7π 4 π 7π 4 11π 4 7π 4 -60 -40 -20 0 20 Find the associated Fourier series X[k] and enter its value for k = 2. 40 7T 4 60 11T 4 80 f(Hz) Consider a signal x (t) whose Fourier transform X(f) is given below.
